Bc it known that I, JAMES P. CMIINGSQOE lewpout,v in theceunty ofCampbell, end Stute of Kentucky,

have invented a new and, usefhl Improvement in Fire-Plugs; and I" doliereby'declureA the following to be a.Y

accompanying drawings, formingpart of thisV specification,'and'invsihich-A Figure l represents longitudinal section of ahrc-plugembodyingniy improvements.

Figure 3, perspective view of-the valve.

Figure'; a, perspective view of the stuffing-box, guid'ea.nd'stop; and*Figure -nn lelevation of the stock. i i v a, may represent the-stock; b,the valve-scat; c, the vulve; d, the waste-stop; e, the waste-hole inthe leg of the vlvmf,4 thewaste-hole inthe stock; g; the rod'g. z, thecup g', z', the nut; j, the end of the nut, projecting above the cap; k,the stuirlngbox, guide; and stop; l5 the flange on the stuffing-box; in,theslot in vthe guide; fn, the block in the-slot; o, the pin holding theblock on the rod; undp, the nut holding the valve on the rod:

The stock a is made ofcast iron orl other metal, of any desired size ordesign as to outside* appearance, and is connected to the water-pipe in'the ground at A','1ind may be either screwed. fast,-as shown Vinthe-drawing, or boted;A Upon the lower end', or that which is connectedto the water-pipe, is placed the valve-seat l, fornied by fittings. woodor gum ring into'a. 'groveturncdin the end of the stock. i

The upper end of'the stockabovegr'ound is formed with a. flange, to'which is fittedv the cap, L, which is. held in place by bolts'.' Inthetop of the cap u recess is made to receivethe nut z', in which is@thread to fit the screwon the upper cnil of the rod g. Thenut z' hasecollar, upon which it rests onthe bottom of the recess in the cap,and`is long enongh'to allow it to'project out-of the top of thecap, andvfornire. square on the end at iffor'th-e reception of n wrench by whichto operate the vulve; In- .the recess in fthe cap is cut u thread, intoVn'hich'is screwed a washer., Vpassing oyerthe nut until it beurs upontheeollur on the nut;r The nut is thus held in place, 'and` allowed torevolve between thewasher und bottom of the recess. I I

'uleleaxg and exact description of the construction and operation of thesuine, reference being had top the Under the cap [is placed the combinedstuingbox, guide, and stop c, which `are forrned vull in one piece,.having a`llangeon the upper end, Z, and held in pince by boltspnss'ingthr'ough the unge on the stock d. Its lower part projects downinto the stock, and has un elongated slot, m, cast in it which forms theguide'oud stop.

Y A The rodg passes through the stu'ing-box and guide in the centre.Upon the rod g and in'the slot m .is

placed the blockn, throgh which the rod also-passes, the blockbeing-held fast tothe rod by the pin o pussing through them. On'the.lower end of the rod is placed the vulve c, made of brass or othermetal, and heving 'four leg-sor Vwings,connect-ed:it their Iupper endsby a. ring, in order to strengthen them. 'The end of theistock is boredout, and the vulve-legs turned ol`,` sons tomake a t. v

v Fornied-inLn-widened portionof oneof thelegs is a'depression, aboutone inch in diameter and one-quarter deep, communicating with theinterior of thcrulifeP by ineens of a' contracted aperture. `A disk, ofgum, leather, or other' suitablcsubstance, being placed inthe-depression, forms thev wastestop d, und below said waste-stop isdrilled thefwastc-hole the distance betweenlsu'id waste-stop'andwastelhole being determined bythe distance the vulve'moves. Directlyopposite the waste-hole e, when the valve is closed, or opposite thewaste-stop d when the valve is opened,is*frilled the wustr-hc'xlef-inlthe stock.` The rod passes through the centre ofthe valve,- andis heldby the ut'p on theend of the'rod, and closesL against the'valve-seut blThe plug being closed, n wrench is Vapplied at the square on thev end ofthe nut z', by turning which the vulve c is made to open, the block nsliding down the slot in; The blcck, being held f ast to the rodvg bythe pin 0,:the rod vis prevented from turning or getting out of place,The block, being screwed down to the-bottom ofthe slot, lstops againstthe gui'de. .The wasteLstop d being brought oppositeithe waste-hole f,in the stock a, the pressure of the water pussing through the plug, andout of thedischnrge-screw acting egalinst the leather or gum in saidwaste-stop through the small hole in the bottom of itscontaining-depression, Ipressing it up tight against the waste-holef inthe stock, and thus preventing any water from wasting. In closing, thewaste-hole e in the leg of the valve will be brought up opposite thewaste-hole f in the stock, and the water remaining in the' stock)allowed to vrun out, and thus prevent the freezing up of the plug incold weather.

What Iy claim as my invention, and desire' to secure by Letters Patent,is-

1. The stuiing-box, guide,'a.nd stop 7c, in combination'with thel blockn and rodgfsubstantially as described.

2. The stop d and waste-hole e, formed in one of the legs of the valvein the manner explained, and arranged relatively to the waste-opening fin the stock, and the valve-seat b, to operate in the manner and forthe`pur pose specified. i

3. The stuffing-box, guide,4 and stop lc, and' block in, as arranged inrelation to the valve e, substantially as described. i
